On Sunday, August 20, 1967, the Fillmore Auditorium was in the last nights of BG-78 - Jim Blashfield's "A Week of Great Music" poster (Aug 15-21), a single sheet that carried Chuck Berry, the Charles Lloyd Quartet, the Steve Miller Band, the Young Rascals, "Hair," and Count Basie & His Orchestra across the week (poster and week span per wolfgangs, which catalogs BG-78 Aug 15-21 and credits Blashfield). The Basie and Lloyd nights fell at the week's end - a big-band jazz elder and a young modal-jazz crossover star sharing Graham's psychedelic hall (the specific per-night placement is COAU's reading; the poster gives only the week range, so treat the Basie/Lloyd-on-the-20th detail as likely rather than settled). The earlier nights of this run - Chuck Berry's - are told on the August 16-19 pages.
